SPECIFICATION forming part of Letters Patent No. 759,756, dated May 10,1904.

Application tiled Uetober 24,1902. Serial No. 128,524. (No model.)

To atl/L wlw-nt may concern,.-

Beit known that I, ALEXANDER SCHNEIDER,

a citizen of the United States of America, and

a resident of Whitebear, in the county of Ramsey and State of Minnesota,have invented certain new and useful Improvements in Switch-Rail Locks,of which the following is a specification.

My invention relates to improvements in switch-rail locks, and has forits object to provide a simple and effective lock for railroadswitches.This result is produced by a studbolt on the side of one of theswitch-rails which projects through an opening in the web of the mainrail and a key passing through the outer end of said stud-bolt.

In the accompanying drawings, forming part of this specification, Figurel is a plan view of a section of railroad and switch, the latter shownin open position and provided with my improved lock. Fig. 2 is acrosssection of a main rail and switch-rail in closed position, showingmy improved lock. Fig. 3 is a plan view of Fig. 2. Fig. 4L is a detailsectional view of a switch-rail, showing the stud-bolt attached thereto;and Fig. 5 is a perspective view of the key used with .my improved lock.

In the drawings let A and B represent the main rails and C and D theswitch-rails, which are of ordinary construction. My improvedswitch-lock, as shown, is attached to the switch-rail C and consists ofthe stud-bolt 2, which projects from the side 3 of the switchrail and isthreaded at I into its web. The threaded end of the stud-bolt is upsetat 5 for the purpose of fastening the stud-bolt securely to theswitch-rail. The web 6 of the main rail is provided with the opening at7 to admit the end of the bolt when the switchrail C is closed, as shownin Figs. 2 and 3. rIhe outer end of the stud-bolt is slotted at 8 toreceive the key E, which rests horizontally against the side 9 of theweb when the switch is locked. The key E, as shown, is a iiat piece ofmetal formed with the stop-shoulder at 10 on one end and the perforation11 on the other end for fastening a padlock 12.

In use I preferably attach the key and lock,

respectively, by means of the chains 13 and 14 to the ties 15 of therailroad, so that the loose parts of the lock will not be lost orcarried away. The switch-stand F may be of any ordinary construction andis connected with the switch-rails C and D by means of the switch-rods16. In operation when the switch is closed the stud-bolt projectsthrough the web 6 of the rail, as shown in Fig. 2. The key E is theninserted through the slot 8 and the padlock 12 fastened, through theperforation 11 of the key. 'I he switch-rails are thus fastened securelyin closed position. l/Vhen the switch is opened, the padlock is unlockedand removed, the key E withdrawn, and the switch-stand F operated in theordinary manner, so as to open the switch-rails C and l) to thefull-line position. (Indicated in Fig. l.)

Having described my invention, what I claim as new, and desire toprotect by Letters Patent, is-
